I have 2 avr studio projects: 1 using the generated makefile and one using an external makefile. I can always open a source file from the build window with the generated makefile project, but not with the external makefile.
I noticed that the generated makefile must change to the "default" output directory when runnign GCC so compile errors are reported as "../sourcefile.c:119 ..." But my custom makefile builds in the same directory as the .c and .aps files. So errors just look like "sourcefile:119".
Has anyone else seen this? Do custom makefiles need to report GCC errors relative to the output directory?
